Do you want to perform component tests at high strain levels and a large number of load cycles? Do you need precise test results in potentially explosive atmospheres? K-OR is a fiber Bragg technology-based strain gage rosette – one of the smallest in the world, however, tolerating extreme loads.
Precise results – even in adverse environments
Since optical strain gages do not require any electrical signals, they open up new opportunities for use in experimental stress analysis. Unlike linear optical strain gages, K-OR – comprising three strain gages – measures strain in three directions. This enables the absolute value and direction of mechanical stresses to be determined in the same way as with electrical strain gages. Specially tested for applications with a strain of ± 5000 µm/m and 10 million load cycles, K-OR in addition withstands extremely adverse ambient conditions.
The optical rosette is highly suitable for measurements
- In potentially explosive atmospheres
- In areas where there is high voltage or
- Powerful electromagnetic interference as well as for
- Materials testing, for example, on the rotor blades of wind power plants.
Easy installation and fast wiring
The installation effort of optical strain gages such as K-OR is similar to that of electrical strain gages. Wiring, however, is less complex, because optical strain gages enable multiple sensors to be connected in one optical fiber.
